Chapter XLVIII.—Thalassius is ordained Bishop of Cæsarea in Cappadocia.
About this same time, under the seventeenth consulate of Theodosius,[1]
Proclus the bishop undertook the performance of an act, such as no one
among the ancients had done. Firmus bishop of Cæsarea in
Cappadocia being dead, the inhabitants of that place came to
Constantinople to consult Proclus about the appointment of a bishop.
While Proclus was considering whom he should prefer to that see, it so
happened that all the senators came to the church to visit him on the
sabbath day; among whom was Thalassius also, a man who had administered
the government of the nations and cities of Illyricum. And as it was
reported that the emperor was about to entrust the government of the
Eastern parts to him, Proclus laid his hands on him, and ordained him
bishop of Cæsarea, instead of Prætorian Prefect.
In such a flourishing condition were the affairs of the Church at this time. But we shall here close our history, praying that the churches everywhere, with the cities and nations, may live in peace; for as long as peace continues, those who desire to write histories will find no materials for their purpose. And we ourselves, O holy man of God, Theodore, should have been unable to accomplish in seven books the task we undertook at your request, had the lovers of seditions chosen to be quiet.
This last book contains an account of the transactions of thirty-two years: and the whole history which is comprised in seven books, comprehends a period of 140 years.[2]
It commences from the first year of the 271st Olympiad, in which Constantine was proclaimed emperor; and ends at the second year of the 305th Olympiad, in which the Emperor Theodosius bore his seventeenth consulate.[3]
